It i is the obj ect of -my invention to 3pm vide 'a boxf which 1 canbe, readily moved froidkcO-llapsed Lfl'at position to assembled b i'ifornif='-- It 1s a 'further object of my invention to provide a corner lock which-"will 'be ea-sily assembled,:bi1t"-which, whenonce assembled,

will stayassembled and willnot pull apart. flt-i'sfniy further object to provide a cor-' nerdOckf-Wliichj-will notonl'y stay locked by ;=reas0n;0i itscOnstruction but also by regasonofiits specialform of'edges. Itis myfurther object to; provide a foldingbox thatwill'bestrong, easily assembled aiid'rigid iii construction; so that the weight of'the contents 'ofth-e box will not so warp the box as tounlock its corners.

' Referring tothe drawings:

1 outside elevation of a Figure 3;

Figure 5 is a section on the line 55'of v Figure 3; v

Figure 6 is a planview of the corner of the box in unfolded condition; Y Figure 7 is a perspective from the outside of the corner showing the corner just being folded with the locking flap being inserted in the locking slit;

Figure 8 is a perspective of the corners of the top and bottom of the box 'whichare just about to be telescoped to form a complete closed box. 7 o Referring to the drawings in detail, 1 is he top of a box having an end wall 2 and side wall 3. For thepurpose of convence, I have not shown the other end wall 1 the other side wall. he end wall, as will be seen in Figures 6 7 somewhat more clearly, is provided h an end flap 4 which has a diagonal 'ng slit 5 provided with a serrated rough e 6 which is so corrugated as to form tchet-like surface for frictionally engag with the locking flap. I his locking slit'starts at the corner crease vhich is the crease between the end flap Figure 1 is an outside perspective of a Figure 4 is asection on the line 44i of nd the end of the box 2. The locking proceeds from the middle point of the QQMBAN'Y'QF 24 0 1, OHIO, A'CORPORATION or OHIO.

"aphasia-11 M J1me 10, 1 2 w 1915.111? i 1 crease inv theaendtflap 4 outwardly and hiterally towards the-outer edge 8 of the flap.

This end. flap is separated from theiside I wait 3- byitheserrated edge 9. The side wall is provided on'its endv adjacent the: end flap adjacent its outer margin with a locking flap 16 having a serratededge; This lock-'- i-ngflap is formed on one side by the cut 9' and on the other side by av serrated slit 12.

The locking flap 10 has its outer edge 11 disposedinwardly of the extreme edges 13 and 14 of the side wall '3 and the end flap. The corner lfrof the locking flap is so ar-' ranged as-to'its'distance from the corner 16 that it will pass into-the slit 5 at its outer end 17' as the end flap ispassed insideof the side wall 3 when the folding'of the box takes: place and thelocki 1g operation of the lock isexecuted.

As will be seen from the drawings, when the locking flap 1O enters the slit 5, it progresses until the end wall. and side wall are atright: angles to one another and the. corner 18 of the locking flap has passed by the corner 17 of the locking slit and is hooked behind it, whilethe edge9 of the locking flap 10 is in engagement with the inner corner 19 of the locking slit.- There is, of

course, a crease 20 between the top and side wall, as well as the crease 21 between th top and end wall 2.

When the box is in folded condition, the end flap is within the side wall with the exception of that portion of the end flap which lies outside of the diagonal locking slit, which portion is designated 22. This is on the outside of'thelocking flap '10.

It will be understood that, when I refer to the top. ofthe box, when the corresponding half of the box is made, this top may become the bottom.

It will be further understood that the I edges are serrated or notched, so that their corrugated surfaces will engage with'one another to provide extreme frictional engagement between the paper parts to prevent disengagement of them.

It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to varying conditions and uses.

Having this fully described my invention, what I claim as new and desire to secure by Letters Patent, is

.1. In a paper box, a bottom portion, a

iii

Ill)

side wall portion, an end wall portion, an end llap having aloeking slit and a locking liap carried by the side wall said locking llap having a plurality f integrally formed,

relatively small, evenly spaced teeth formed on the edge thereof.

in a paper box, a bottom portion, a side all portion, an end wall portion, an end liap having a locking slit and a locking flap carried by the side wall, said flap and slit having their edges formed into a plurality of integral, regularly spaced teeth of relatively small size.

3. In a box, a body portion, an end Wall portion, a side wall portion, an end flap portion having a diagonal lot-king slit and a rectangular leeking .tlap portion on the end wall portion, said slit and locking tlap portion having edges jl'orined into a plurality of integral, regularly spaced teeth of relatively small size.

-l. In a box, a top portion, an end wall, a side wall, said end wall having an end flap hinged thereto extending across the end oi the side wall and having a locking slit, a locking flap termed parallel to the end flap and as a part of the side wall of the box, the edges of the locking flap and the slit being formed into a plurality of integral. regularly spaced teeth of relatively small size.

in a paper her having a belly portion, end and side walls locked together at the corners constituting a corner lock, edges on "tending across the en the locking portions thereof to resist the unlocking thereof, such edges being formed into a plurality of relatively small teeth with the ends of the teeth spaced from one another.

(S. In a box, a body portion, an end wal portion, a locking fla hinged thereto exi of a side Wall portien, a side wallportion, a locking flap interposed between the end flap and the side wall portion, said end flap having a locking slit, and said locking fla and end flaphaving adjacent edges, anc said locking flap and side wall portion having adjacent edges, all of the edges of said parts being formed into a plurality of small finely spaced teeth of uniform size. a

7, In a paper box, a bottom portion, a side wall portion, an end Wall portion, an end flap having a locking slit and aloeking llap carried by the side Wall, said locking slit having edges formed into a plurality of small evenly spaced uniform sized teeth.

8. In a paper box, a bottom portion, a side portion, an end wall portion, anend flap having a locking slit and a locking flap carried by the side Wall, all of the exposed edges and the locking slit having edges formed into a plurality oi relatively small evenly spaced teeth.

In testimony whereof, I alfix my signal u re.
